초록 ▼

An improved power plant employing a combination of compressed air storage and saturation (simultaneous heating and humidification) of compressed air is disclosed. The power plant includes a combustor which provides hot gas for driving a turbine. The turbine is used in conjunction with a generator to generate electrical power. The power from the turbine is accessible by a compressor system during low power demand periods. The compressor system is used to compress air which is stored in an air storage chamber. The compressed air from the air storage chamber is used by the combustor during high power demand periods, while the compressor system is shut down, to provide compressed combustion gas to the turbine. To enhance the efficiency of the plant, while further lowering the capital cost of the plant, a saturator is positioned between the storage chamber and the combustor. The saturator receives compressed air from the storage chamber and simultaneously heats and humidifies it. The resultant heated and humidified compressed air is then conveyed to the combustor, typically after further heating by a recuperator.
